special conditions: arise because of the consider able length of thehair, the soft falling-over of the hair, and the natural fallingdirection of the 10' hair. These conditions distinguish fur skins fromother material from the standpoint of cutting out patterns.

Only such productions of patterns have consequently hitherto been knownwherein the pattern appeared in quite a simple form, as for instance,stripes running out in the direction of the fall of the hair.

The present invention has as its object the cutting out of any desiredkind of pattern in fur 3O skins, the pattern being all around borderedand being, if desirable, crosswise to the falling direction of the hair.Thus are obtained fashion effects considerably surpassing the hithertoknown ones in beauty and rich variety. As the manufacture of fursrepresents a trade with a great demand for changes in fashion, acorrespondingly great industrial advance is due to such process.

The process consists mainly of a template of sufficiently stiff materialsimultaneously passed with the fur skin to be cut in front of a cuttingdevice in suitable manner. The cutting device operates in conjunctionwith novelly conceived means of straightening and drawing the hairsthrough the apertures of the template. The device according to thepresent invention consists on the one hand of the mentioned templatecontaining the parts of the surface intended to be cut out of the furskin in shape of recessed holes, and on. the other hand of novelarrangements for practical operation of the said template in conjunctionwith the straightening and drawing means for the hairs.

One embodiment of the invention is described below wherein one of thecustomary fur-cutting machines is used. It is however easily seen thatthe invention may be applied to other desirable types of fur-cuttingmachines.

In the drawing accompanying this specification and showing preferredembodiments of the invention, Figure 1 is a longitudinal section throughthe parts of a fur-cutting machine involved in the invention showingother cooperating and novel parts. Figure 2 is a view of the structureset forth in Figure 1 in plan, the casing of the flu-cutting machinebeing shown in cross-section.

In accordance with the drawing a, a are transport rollers, being drivenin the usual manner either by hand or motive power and moving theconveying belt b along to and in front of the cutter.

c is a stationary knife cooperating with a revolving circular cutter d.A suction-pipe line e to the air-propeller removes the air in thedirection of the arrow thereby raising the hair of the fur tobe cut outin front of the cutter and drawing the same in as far as the hair is notcovered by a template f. The template 1 as shown is in the shape of arectangular plate. The material of the template is flexible and yetstiff enough to prevent possible corners from projecting into thepattern apertures, and being bent in the direction of the cutter wherethe said corners could be caught by the same. iron as Well as cardboard,celluloid or the like is. suitable for this purpose. The bending of suchprojections of the template f in the direction of the cutter is therebymade Well-nigh impossible, being furthermore insured against thiscontingency by suitable guiding means for the template. Thus, thetemplate is made to rest firmly upon the surface of the fur-skin in itspassage, thereby covering the fur skin with the desired pattern. As anexample, the template 1 is guided by lateral guide-rails g, g so thatthe template passes close in front of the fur skin, the template beingbetween the latter and the cutter as the fur skin itself is passedaround the guide roller a. friction with the fur skin; by suitablecooperation with lateral portions of the guide roller and/or theconveying belt; by gear transmission or other known means, the movementbeing effected with exactly the same speed with which the fur skin movesor at other desired relative rates.

The templates are generally made so large-that their length suifices forthe passage of a furskin h. Before the next fur skin h is: fed forward,the template I is returned to its upper starting-position by eitherwithdrawing the same entirely from the guide and inserting it again fromabove, or drawing the same back into the guide by reversing its formermoving-direction. In order to prevent the template from dropping tooquickly consequent to its weight, a compensating-weight i is fastened toit and suspended over a roller is. If the weight is made sufficientlylarge, an upward pulling force is produced,

Metal or Moving the template ,1 can be effected by i whereby thetemplate is automatically moved back as soon as the motive force ceaseswhereby it has been moved down during the cutting process. Instead of apull by weight, a tension-spring or any other suitable device may beused.

The manner of transport of the fur skins toward the cutting tool can beeffected in many ways. The skin or skins may lie permanently upon theside of the template away from the cutter, or may be in contact with thetemplate only at the moment when the template passes the cutter, asshown in Figure 1.

I wish it understood that minor changes and variations in the selectionof the known cooperating members of the invention together with theirintegration and location may all be resorted to without departing fromthe spirit of the invention and without departing from the scope of theclaims.

I claim:

1. In a device for cutting out patterns in fur skins, the combination ofa cutting tool, an apertured and resilient flat template, means to movethe said template in front of the said cutting tool in a plane, means tofeed and secure the skin against the template for simultaneous movementwith the template while the latter passes in front of the cutting toolthereby allowing the free hairs to penetrate through the aperturestoward the said cutting tool, and means to raise and draw the free hairsextending through the apertures of the template toward the cutting toolduring cutting operation.

2. In a device for cutting out patterns in fur skins as described, thecombination of a fiat apertured template of stiff material, theapertures of which represent all around bordered designs, a cuttingtool, means to move the said template whereby the template is, duringcutting operation, moved in approximately a straight line along and infront of the said cutting tool, and

means to raise and draw the free hairs extending through the aperturesof the template toward the cutting tool during cutting operation.

3. A construction as defined in claim 1 wherein the last mentioned meanscomprises a suction chamber formed with the cutting tool.

4. A construction as defined in claim 1 wherein the last mentioned meanscomprises a vacuum chamber communicating with and rearwardly of thecutting tool.

5. In a process for cutting out patterns in fur skins, the steps ofdepressing hairs on selected portions of the skin against an aperturedtemplate moving in a plane, raising and straightening out theundepressed hairs, and cutting off the said hairs so straightened out.

6. In a process for cutting out patterns in fur skins, the steps ofdepressing hairs on selected portions of the skin by means of a fiat andapertured template moving along a plane, raising and straightening outthe undepressed hairs through the said apertures, and cutting ofi thehairs so straightened.

7. In a process for cutting out patterns in fur skins, the step ofraising and drawing in selected portions of hairs through the aperturesof a flat template moving in a plane across a cutting tool.

8. In a device as described for cutting out patterns in fur skins, thecombination of an apertured and resilient flat template moving in aplane and means to raise and draw the free hairs of the fur skinsextending through the apertures of the said template.

9. In a device as described for cutting out all around borderedpatterns. in fur skins, the combination of an apertured and resilientfiat template moving in a plane, a cutting tool and means to raise anddraw the free hairs of the fur skins extending through the apertures ofthe said template toward the said cutting tool.
